    2. Relevant equations


    3. The attempt at a solution


    Magnetic field due to both semi - infinite straight wires on P = Magnetic field due to infinite straight wire on P = ## \frac { \mu_0 I } { 2 \pi a } = 2 * 10 ^{-5} ~wb/m^2 ##

    Magnetic field due to semi – circular wire on P = ## \frac { \mu_0 I } { 4a} = 3.14 * 10 ^{-5} ~wb/m^2 ##


    So, total magnetic field magnitude on P is = 0.514 gauss.

    Is this correct?
